 A cross-platform desktop Nostr client built with Tauri 2.0 + React + TypeScript. Polished UI, deep Lightning integration, and first-class support for long-form writing.
 
-> Named as a nod to Nostr with a wry twist.
+> Named after Jurij Vega (1754–1802), a Slovenian mathematician who made knowledge accessible through his pioneering logarithm tables — just as Vega makes writing accessible on Nostr.
